功能：

1、添加联系人

2、显示联系人

3、删除联系人

4、查找联系人

5、修改联系人

6、清空通讯录

0、退出通讯录

上代码：

#include<iostream>
#include<string>
using namespace std;
#define MAX 1000
struct Person
{
	string name;//姓名
	int sex;//性别：1 boy;2 girl
	int age;//年龄
	string phone;//电话
	string addr;//住址
};

struct Addressbooks
{
	struct Person personarray[MAX];
	int size;
};

//添加联系人
void AddPerson(Addressbooks* abs)
{
	//判断通讯录是否已满
	if (abs->size == MAX)
	{
		cout << "通讯录已满" << endl;
	}
	else
	{
		string name;
		cout << "请输入姓名：" << endl;
		cin >> name;
		abs->personarray[abs->size].name = name;

		int sex = 0;

		cout << "1--男" << endl;
		cout << "2--女" << endl;
		while (true)

			if (sex == 1 || sex == 2)
			{
				abs->personarray[abs->size].sex = sex;
				break;
			}
			cout << "输入有误，请重新输入！" << endl;
		}
		int age = 0;

		abs->size++;//更新通讯录人数
		cout << "添加成功！" << endl;

		system("pause");//按任意键结束
		system("cls");//清屏
	}
}

//显示联系人
